Me? A Human Backboard?

I have finally received a really great tennis compliment - I've been called a "human backboard"! I played a doubles match last week that went so well - I had a great partner who played the same style of tennis that I like to play (aggressively and at the net), we had nice opponents who gave us a challenging game (one of them was a leftie!), and we had to fight to win the match in a second set tiebreaker (6-4, 7-6 (7-3)).
After the match, as we were recording our scores, I was talking to one of my opponents about what a nice match we'd had and how I felt like it could easily have gone the other way. And she said, "Oh, we couldn't get anything past you. You returned everything. You're a human backboard!" Me! A human backboard! It was the cherry on top of the fluffy white frosting on top of the angel food cake of my tennis match that day! Thank you opponent-whose-name-I-can't-remember for the best tennis compliment I've received in a long, long time. (For the record - I do not believe I am a human backboard but if this lady wants to go around saying stuff like that, who am I to stop her?)
